The longlived charged massive scalar field in the higher-dimensional Reissner--Nordstr\"{o}m spacetime
The quasinormal resonance frequency of the higher-dimensional
Reissner--Nordstr\"{o}m (RN) black hole due to charged massive scalar field
perturbation is deduced analytically in the eikonal regime. The characteristic
decay timescale of the charged massive scalar perturbation in the background of
the higher-dimensional RN spacetime is then obtained. The result reveals that
longlived charged massive scalar field can exist in higher-dimensional RN
spacetime under a certain condition.Comment: 6 pages, 1 figur
